though, there's an answer from the bottom up to the question
about how well we can come to an agreement on what is uni-
versal. I've posted a couple of reviews of Brown already
(although I can't seem today to find any of them on-line;
perhaps more on that, later), so I'll confine myself now to
recommending it both as a well-written, well-edited mono-
graph, with a useful bibliography occupying almost fifty
pages, and also as a pedagogically-valuable introduction to
the anthropologic enterprise. Some ideologues have accused
Brown of committing sociobiology, but this work, at least,
is sophisticated and thoughtful.
